Likely interview questions for this role

Written from this job description, not a generic list. Each one notes what the interviewer is really checking.

Behavioral

Tell me about a SIOP supply review meeting you led where there was a real disagreement between sales and manufacturing about what could actually be produced.

experience facilitating cross-functional conflict and whether they can drive to a decision, not just present data

Describe a time you found a gap between your supply plan and what actually happened on the floor. What told you something was wrong, and what did you change?

root-cause thinking and whether they close the loop on planning accuracy

Tell me about a time you had to push back on manufacturing capacity assumptions that sales or leadership had already committed to externally.

willingness to deliver unwelcome constraints and how diplomatically they do it

Tell me about the most complex multi-site supply chain problem you've had to untangle. What made it complex, and how did you keep stakeholders aligned while you worked it?

scale of prior experience and stakeholder communication under real complexity

Tell me about a process improvement you drove in a planning or SIOP process that stuck, not just one you proposed.

evidence of actually implementing change and getting it adopted, versus theoretical improvement ideas

Technical

Walk me through how you build a supply plan from a demand forecast when you're coordinating across multiple manufacturing facilities like Berlin, Beaver Dam, Allmand, and Enercon.

whether the candidate actually understands the mechanics of translating demand into an executable, site-specific supply plan

How do you use SAP to manage planning parameters, and can you give an example where bad planning data caused a problem you had to fix?

depth of hands-on SAP/MRP experience versus surface familiarity

What KPIs do you use to know your supply plan is actually working, and how do you build a dashboard or Power BI report that people at different levels will actually use?

whether their reporting instincts are built for decision-making, not just data display

How do you set and maintain planning parameters like safety stock, lead times, and lot sizes in MRP, and how often do you revisit them?

understanding that MRP quality depends on ongoing parameter discipline, not a one-time setup

What's your process for documenting planning assumptions and supply risks so someone else could pick up your work if you were out for two weeks?

whether they build durable, transparent processes versus tribal knowledge

Situational

Say a key material for one plant is suddenly constrained and it's going to blow the production schedule for two other facilities that share the supply. What do you do first?

how they triage multi-site risk and prioritize communication versus jumping straight to a fix

A new product introduction is about to ramp at one of the plants and it's going to compete for the same materials and capacity as an existing high-volume line. How do you plan for that?

ability to balance NPI support against protecting core production commitments

If inventory targets and customer service goals are pulling in opposite directions for a given product line, how do you decide where to land?

judgment on tradeoffs between working capital and service level, a core planning tension
